Caldav (personal) binding

hey there,

i got another question. I read the caldav binding documentation. What means

"First of all you need to add the to the addons folder.

Newest Newest Version can be downloaded from the build-agent"?

Do i have to install or copy something to addons-folder before i install this binding? If yes, where can i find it?

The docs regarding caldav are a little bit misleading sometimes:

just install the binding the usual way from PaperUI:
